Paint Spraying Tips & Techniques
- Humidity and Weather Conditions:
- Avoid painting in wet or humid conditions to prevent poor finish quality. If the clearcoat dries with a whitish haze or streaks, it indicates that the humidity is too high for painting.
- Temperature Considerations:
- Ensure the ambient temperature is at least 70°F but not exceeding 80°F. Temperatures over 80°F can cause the paint to dry too quickly, potentially before it reaches the surface, resulting in a rough texture.
- Direct Sunlight:
- Do not spray paint in direct sunlight as it can accelerate drying times excessively, affecting the paint’s finish.
- Preparation:
- Spraying the Basecoat:
- Apply even, overlapping coats, ensuring the painted area is evenly wet without dry spots.
- Let the first basecoat dry for about 20 minutes before applying the second coat.
- Allow the basecoat to dry overnight.
- Sanding and Final Coat:
- Wet sand the area using 1000 grit wet and dry sandpaper to smooth out any imperfections or dust.
- Apply a final coat of paint over the area but do not sand this coat.
- Let the final paint coat dry thoroughly before applying clearcoat, usually overnight. In temperatures below 70°F drying may take longer.
- Clearcoat Application:
- Ensure the basecoat is dry to the touch before applying the clearcoat.
- Shake the clearcoat can for two minutes before use (note: this can does not contain a metal mixing ball).
- You would typically spray the clearcoat farther out than the paint to a panel line on your vehicle. Again, you don’t want to spray the clearcoat in the middle of a panel without going out to the edges as you will leave a noticeable clearcoat line. Use blender for better results.
- Apply the clearcoat evenly over the base paint. Avoid spraying in direct sunlight or on parts that have been heated by the sun to prevent a dull finish.
- Allow the clearcoat to dry thoroughly. Overnight drying is typically sufficient, but in temperatures below 70°F, it may take longer.
- If imperfections are present, wet sand with 1000 grit sandpaper, then apply a final coat of clearcoat.
- Let the final clearcoat layer dry for at least three days.
- Use our automotive rubbing compound (cutting creme) to polish the area and enhance the shine.
- Adjusting Paint Shade with Clearcoat Application
- Technique to Lighten Paint:
- Hold the spray can further from the surface during application to subtly lighten the paint shade.
- Technique to Darken Paint:
- Hold the spray can closer to the surface to darken the paint shade.
- Testing and Practice:
- Practice these techniques off the vehicle to master the effect and gauge its impact on your specific paint color.
- Catalyzed Clearcoat Considerations:
- Be aware that catalyzed clearcoat dries quickly due to the catalyst, especially under warmer conditions.
- Always review and follow the instructions on the can prior to use for optimal results and safety. Be sure and wear an approved NIOSH respirator. This stuff is very toxic.
- Paint Spraying—Paint to an Edge:
- After painting the repaired area, feather the paint out slowly on either side to blend with the existing paint seamlessly.
- Professional shops often paint to a boundary such as the edge of a door or a panel line to avoid leaving a visible paint line.
- Notes on Spraying Metallic Paints:
- For best results, blend metallic paints into the surrounding areas.
- Avoid applying too much paint or reducing the time between coats, as this can make the metallic flake uneven.
- Spray the final coat of metallic paint from a farther distance to ensure even distribution of metallic flakes. Practice off the vehicle to find the optimal distance.
- Watch for Drips:
- If a drip occurs during spraying, do not attempt to wipe it off. Allow it to dry, then sand it out and reapply the paint.
- Consider wrapping the spray can with a rag to catch any unforeseen drips and regularly check the nozzle and can for excess paint build-up.
